FAQ
Do you need access to my live store?
Not for development. I build and test on a development store, then install on your live store as a collaborator for final deployment, the safe way Shopify recommends.
Private app or public app, which one do I need?
If it is just for your store, a private app is faster and cheaper. If you want to sell it on the Shopify App Store, I build it review-ready with billing API and GDPR webhooks.
Can you add features to my existing theme instead?
Yes. Many requests are solved with a theme app extension or a custom section rather than a full app. I always recommend the cheapest option that does the job properly.
Will the feature survive theme updates?
Yes. I build features as app blocks and extensions rather than editing theme files wherever possible, so your customizations survive theme changes and updates.
